The Garmin, when not trying to communicate with another device is only listening to satellite signals.
I think what Bosch has in mind is that if you add the cadence, speed etc. ANT+ sensors to the Garmin, they might not be available to the Bosch unit. I don't know if this is true (i.e., that a Garmin would "hog" the device connection), having never tried it, but I think that is what the Bosch head unit is warning against. Ideally, it would be nice if the user could use both simultaneously.
